How can I make this work?

I’m looking at going to Cosmetology School, I have two babies 2 year old and 3 month old. My closest schools are an hour away in any direction. How do I make this work? I’ve thought about this since highschool and I feel like I’m ready to take the nexts steps to get there I just don’t know how. If I do this I can’t work so I can’t afford a sitter, and my fiancé works the hours the school is open but we make just enough to get by
